From b99c6ebe8f53dce1f56f0d483f6a7c23edb19d4c Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 18 Jun 2009 01:44:19 -0700 Subject: sparc64: Fix UP bootup regression. Commit b696fdc259f0d94348a9327bed352fac44d4883d ("sparc64: Defer cpu_data() setup until end of per-cpu data initialization.") broke bootup for UP builds because the cpu_data() initialization only occurs in setup_per_cpu_areas() which is never compiled in nor called in UP builds. Fix this up by calling the setups directly from init_64.c when non-SMP. Reported-by: Alexander Beregalov Tested-by: Alexander Beregalov Signed-off-by: David S.
